The decision
Should Martian make your shortlist?
Start with the job, the team, and the constraints. Product fit becomes much clearer when those three line up.
Practical use cases
Jobs it can take on
- Send model requests through a unified API
- Track model usage and request history
- Train and evaluate LLM agents with ARES
Before you choose
Know the tradeoffs
- Gateway access requires a valid API key and available credits.
- Not all models are available in every region.
- The Gateway applies fair-use rate limiting.
Inside the product
What you can actually do with it.
The core product capabilities, grouped around the work they enable.
Martian Gateway
The Gateway provides unified API access to more than 200 AI models and supports OpenAI and Anthropic API compatibility.
ARES
ARES is an RL-first framework for training and evaluating LLM agents, particularly coding agents.
K-Steering
K-Steering is a toolkit for steering language-model behavior at inference time without fine-tuning the base model.
Typical workflow
Developers authenticate with a Martian API key and send a request to the Gateway with a selected model and messages. They can then use the Martian Dashboard to review usage, model performance, and request history.
